As of July 2021, the Nix community offers five variants of GNU Emacs: emacsGit, emacsGcc, emacsPgtk, emacsPgtkGcc, and emacsUnstable. For installing one of them, add the following lines to /etc/nixos/configuration.nix (replace emacsPgtkGcc with the variant of your choice).

{
  services.emacs.package = pkgs.emacsPgtkGcc;

  nixpkgs.overlays = [

    }))
  ];
